I'm putting on my exhaust manifold and would like a gasket thicker than the fel-pro. Who sells that kind. How tight should you get the bolts
I have a 460cid which are notorious for exhaust leaks. I fixed it with a gasket from (I think) Mr. Gasket. They told me that if I add an suffix A after their gasket part number that it would be made out of thicker, soft AL. You should call them to verify.
A machine shop can surface the contact areas of the manifold. Then use clean bolts and Ultra Copper silicone sealant. Bruce
Right---a good machine shop should have a large belt sander to lay it on and get a good flat surface across. You could check them with a good straight edge also.
